Jessica Biel hosted the first of this year’s Oscar ceremonies, the mostly honorary Scientific and Technical Awards, on Saturday night While the 26 year-old looked stunning in her Oscar de la Renta outfit, the accessory she didn’t have was boyfriend Justin Timberlake.

Just bad timing. The actress did throw a surprise 28th birthday party for him last week in the Hollywood Roosevelt Hotel’s penthouse with over a 100 guests. Word is that he still intends to propose real soon. The couple has been dating for 2 years.

Previously, Timberlake had been linked with Britney Spears and Cameron Diaz.

“The older I get, the more movies I do, the more aware I am,” Biel said of the contributions of her tech crews.

In fact, the biggest applause of the evening wasn’t for the hot young star… It was for an award given to Ed Catmull, co-founder of Pixar — which will release its 10th film, Up, in May, and whose WALL-E is expected to snag the best animated feature Oscar on February 22.
